Rebuilding at every stage shouldn't be too bad, with pinned dependencies. I can see problems with it, of course. That said, using a private code publishing location seems the correct path? That isn't too difficult to setup, is it?

That said, I'm still not clear on what difficulties folks are worried about. I'm also not clear I care on the mess of commits getting things working. The initial commits of getting anything working are almost always a mess. Such that worrying about that seems excessive.
